Slip Throughput
Bi-directional line speed is based on a printhead speed of 260 CPS.
Throughput (
±
5%) at the standard line spacing (7.2 LPI) depends on
line length expressed in characters:
Line Length Character Density Lines Per Minute
40 Chars. 13.9 CPI (standard) 290 LPM
52 Chars. 13.9 CPI (standard) 237 LPM
66 Chars. 13.9 CPI (standard) 195 LPM
80 Chars. 17.1 CPI (compressed) 166 LPM
Unidirectional (graphics) line speed, will be half the above throughput.
Top Edge
Minimum 15.0 mm (0.59 in.)
Trailing Edge
Minimum form width for full width print = 127 mm (5.00 in.)
Minimum with Slip Stop 16.0 mm (0.630 in.)
Printable Zone, 330 Full Dots = 120.7 mm (4.752 in.)
Nominal Margins = 3.2 mm (0.125 in.)
